Abstract: A car tray and exercising apparatus for passengers riding in a vehicle is disclosed. The apparatus comprises a tray deployed in a horizontal plane which is supported by a vertical support. The vertical support comprises a pair of rods having an upper end bent in an arcuate manner to form a hook passing over the back of the front seat of the vehicle. The vertical support has a lower end which rests on the vehicle floor. An exercise axle and wheel is rotatably supported by a bore passing through the lower end of the vertical support. The axle has at each end a pair of radial arms extending in opposed directions, each arm is bent at its end at a right angle to project outward from the wheel forming a pedal. A person seated in the rear seat of the vehicle is able to rotate the wheel using the pedals and obtain exercise thereby.
